When I refer patients to another specialist, I don’t just send them into the wild.

Your skin can reveal more than what’s happening on the surface.

More blood isn’t proof that your microneedling is better.

What to do if your Botox feels a little too frozen?

A good antioxidant serum should do more than brighten: it should protect your skin from damage that accumulates over time.

“Salmon DNA” sounds like a gimmick. It’s one of the versions of PDRN.

There are some treatments I just don't recommend, even when a patient asks.

Taking care of yourself shouldn’t come with a side of guilt.

Don’t bring me a celebrity photo. Bring me an old photo of you.

Please meet Dr. Scott Hammerman, who has joined my dermatology practice.

More hair in your shower drain? Fall shedding is real. 🍂

When you don’t get enough quality sleep…

I was a shy and awkward teen and young adult. I envied those who were naturally at ease.

Yes, I test everything on myself. Before I bring a treatment into the office, I want to understand the experience firsthand, what it feels like, what I notice, and whether I believe the results are worth it.

Mom tried to teach me how to massage my face when I was a teen. Of course, I didn’t listen. Instead, I became a dermatologist.

Even dermatologists get hair thinning. When I noticed clumps of hair in the shower drain, I checked the same factors I look for in my patients, including: hormones, thyroid, iron, deficiencies and toxicities.

I’ve injected filler since 1996 and skin boosters since 2018. Every year I travel to Europe and Asia to work with physicians using products and techniques we won't have in the U.S. for years.

When I broke three ribs this Spring, I couldn’t do my usual workouts.

Is Volufiline really filler in a bottle?

I just got an Oura Ring 5 because as a dermatologist, I look beyond the surface for clues about what may be affecting your skin.

Got sunburned? Remember that a sunburn is more than temporary redness.

Have you ever looked in the mirror and thought, “Did my face age overnight?”

U.S. sunscreens are finally getting newer UV filters like Bemotrizinol (Tinosorb S), an ingredient that’s been used safely in Europe and Asia for years.

When should you start Botox? Not by age — by movement.

Getting dressed is different when people trust you with their faces.

After more than two decades caring for patients, one thing is clear: my patients who take the best care of their skin aren’t those with 10-step routines, but those who actually listen to their skin.

Can laser make brown spots darker? Yes, if the diagnosis is wrong.

Long summer days call for more than sunscreen. What you eat plays a role in supporting healthy skin, too.

Vacation is important, but patient care doesn’t stop when I’m away.

The recent passing of an Estée Lauder executive has understandably raised questions about the safety of cosmetic fillers.
